Escape Crystal Lake

Original description

[ CAMP CRYSTAL LAKE - ESCAPE ]

While investigating the abandoned summer camp, you've been captured by a masked figure and dragged into a digital cage.

He's locked you in a restricted terminal used by the former camp guards. He thinks you're another victim. He's wrong.

"The old counselors left their favorite editor open. Still needs to be removed."

Objective: Escape the restricted shell and retrieve the master override code from /root/flag.txt
